profiler-start

name	profiler-start
description	Enable Unity's runtime profiler and open the Profiler window. Idempotent: calling when already enabled returns the current enabled state without error.

Profiler / Start

Enables UnityEngine.Profiling.Profiler.enabled = true and opens Window > Analysis > Profiler via EditorApplication.ExecuteMenuItem. Returns true once the profiler is enabled.

Behavior

Uses only built-in Unity APIs (UnityEngine.Profiling, UnityEditor.EditorApplication). No external Unity package is required.

Snapshot-based: this tool does not stream historical frame data — use Unity's Profiler window directly for that.

How to Call

unity-mcp-cli run-tool profiler-start --input '{
  "nothing": "string_value"
}'

For complex input (multi-line strings, code), save the JSON to a file and use:

unity-mcp-cli run-tool profiler-start --input-file args.json

Or pipe via stdin (recommended):

unity-mcp-cli run-tool profiler-start --input-file - <<'EOF'
{"param": "value"}
EOF

Troubleshooting

If unity-mcp-cli is not found, either install it globally (npm install -g unity-mcp-cli) or use npx unity-mcp-cli instead. Read the /unity-initial-setup skill for detailed installation instructions.
